 A testable idea or explanation that leads to scientific investigation based on prior knowledge is known as: 

• theory
• experiment 
• observation
• hypothesis

What is a testable question that can be answered by an experiment?

• How many animal species live in Australia?

• Why are birds' bones hollow?

• What type of chewing gum stretches the farthest?

• How fast does the Earth rotate around the sun?

• To find answers to their questions

• To become the best scientists

How observations are made?

• With your senses

• With lab tools

• Both of them are correct

Scientists often use visual or mathematical representations to investigate items that are very large, very small, or otherwise difficult to study.  What are these visual or mathematical representations called?

• experiments
• hypotheses
• models
• observations

Models can be helpful in scientific investigations because

• it may not be possible to work with the real thing.

• they can be smaller and more manageable than the real thing.

• they can be safer to work with than the real thing.

• all of the above
